On Part #15 FM, there no actual RF power out limit, but just that limiting FS limit of 250uV measured at 3 Meters away. I do remember that someone in the 1990's Panaxis EBN (Experimental Broadcaster's Newsletter) calculating with the possible RF OUT would be to a 1/4-Wave GND Plane Antenna, and it was something like 600pW - 800pW. That's picowatts, 10 to the -12! That small!!!
